Dental CariesTo evaluate the efficacy of a papain-based gel in caries removal.
Primary Care Beverage Study
ObesityDental CariesThis is a pilot randomized clinical trial of a brief educational intervention offered in primary care for Latino parents that promotes healthy beverage consumption by infants and toddlers. The control group will receive an educational intervention that promotes parents reading to children.
Clinical Performance of Posterior Glass Ionomer Restorations in Adolescents (KETAC)
Dental CariesThe purpose of this study is to determine whether two tooth-colored glass ionomer materials are effective for load-bearing dental fillings.
Effectiveness of Atraumatic Restorative Treatment Using Glass Ionomer Cement of Different Costs...
Dental CariesAtraumatic Restorative Treatment (ART) is an alternative restorative technique for dental caries, applying the partial caries tissue removal philosophy using hand instruments, relative cotton rolls isolation, immediate restoration with Glass Ionomer Cements (GIC) and avoiding local anesthesia. The chosen material for this study will be the High Viscosity Glass Ionomer Cement (HVGIC) due to its unique physical-chemical properties as well as its applicability in challenging clinical situations where other materials would not be adequate. Although there are substantial evidences regarding GIC properties, information about GIC (with different costs) longevity is still weak. Therefore, the objective of this study is to assess the effectiveness of ART restorations performed with low-cost HVGIC in cavitated dentine carious lesions in primary and permanent molars. This will be a multicenter randomized controlled double-blind (patient and operator) clinical trial performed with 680 primary and/or permanent molars in children between 4 and 9 years old presenting cavitated dentine carious lesions in occlusal and occlusal-proximal surfaces. The tooth will be considered as the unit sample, which will be randomly allocated to the groups through a generated random list numbers and distributed in dark sealed envelopes opened only by dental assistants. Teeth in the test group will be submitted to restorative treatment with HVGIC Vitro Molar and those in the control group with HVGIC Fuji IX. The restoration effectiveness will be assessed by means of both clinical and bitewing x-rays control after 6 and 12 months.
Composites and Urinary Bisphenol-A Study
Dental CariesThe Composites and Urinary Bisphenol-A Study (CUBS) is a clinical study of dental composite for its effects on urinary bisphenol-A levels. The study will enroll approximately 139 children recruited from study-affiliated clinical sites in New England.The primary aim of CUBS is to test the hypothesis that urinary bisphenol-A (BPA) concentrations increase after composite restoration placement. BPA is a chemical used in the synthesis of matrix monomers and has been shown to have harmful effects in toxicological studies in laboratory animals. Currently it is unknown whether dental composite restorative materials containing monomers that are derived from BPA result in chronic low-dose BPA exposure in children.
Effect of Dentifrice Usage Regime on Delivery and Efficacy of Fluoride
Dental CariesThis study will evaluate and compare the effect of the amount of toothpaste used and brushing time on enamel strengthening (percent of surface microhardness recovery, % SMHR) and enamel fluoride uptake (EFU).
Local Anesthesia With Computerized Device for Restorative Procedures in Pediatric Patients
Dental Pain and Sensation DisorderDental Caries in ChildrenThe aim of the present study is to assess if there are differences on perceived pain during local anesthesia performed with SleeperOne device or with a traditional syringe in pediatric patients. Patients responding to the inclusion criteria will be asked to participate to the study. After signing the informed consent, they will undergo local anesthesia procedure on first or second primary molars for the subsequent performing of dental filling. The split-mouth design will randomly allocate first or second primary molar from one quadrant to SleeperOne procedure, while the contralateral one will be subdued to local anesthesia with traditional syringe. After the procedure, patients will be asked to assess the perceived pain with a Visual Analogue Scale from a range 0-10. VAS scales will be used to assess sensations of "size" (related to the two instruments), bitter and vomit.
Silver Diamine Fluoride Gel: Case Series
Dental Caries in ChildrenA clinical case series to determine the clinical response of dental caries lesions in primary teeth where 38% silver diamine fluoride gel is applied and cover with 2.5% sodium fluoride varnish. Additionally, to assess parent satisfaction with treatment with 38% silver diamine fluoride.
A Clinical Trial Comparing Isolite® vs. Cotton Roll Isolation in the Placement of Dental Sealants...
Dental Caries on Pit and Fissure SurfaceThe purpose of this split-mouth, randomized, controlled trial is to evaluate the retention rates of sealants placed under Isolite vs. cotton roll isolation. This study will also compare the patient and operator acceptability and satisfaction of the two isolation techniques as well as the time consumed for sealant application during the two isolation techniques.
Checking Occlusion During Stainless Steel Crown Placement
Dental CariesStainless steel crowns are arguably the most successful posterior restorations in primary teeth and have been so for more than 50 years. Stainless steel crowns offer durability and success rates in excess of 95% making them the restoration of choice for posterior primary teeth in children treated under general anesthesia. Failures of stainless steel crowns placed on primary teeth have been documented using several criteria including marginal adaptation, recurrent caries, abscess formation or root resorption, loss of the crown due to faulty retention and even perforation of the crown . Despite the probability that factors such as root resorption and failure of endodontic treatment could be due to traumatic occlusion, surprisingly little evidence is available in literature on the attempts made to check or evaluate the occlusion of stainless steel crowns placed under general anesthesia The aim of this study was to compare the time taken for placement and the overall success of bilateral multiple stainless crowns placed under general anesthesia using an occlusal index and compare them to crowns placed without such an index, using a randomized control study design
